Guideline on Equipment Energy Efficiency
High Efficiency Motor
The most efficienct motors are termed High Efficiency Motors (HEMs)- classified as Eff1 under European Committe of Manufacturers of Electrical Machines and Power Electronics (CEMEP), or their equivalent.
The CEMEP classification standard has been adopted by Malaysia to classify motor efficiencies.
Key design features of HEMs include:
- Improved fan design
-Better slot design
-Improved core design
-Optimised air Gap
Efficiency Classification :
EFF1 (High Efficiency Motors)
EFF2 ( Improved Efficiency Motors)
EFF3 (Standard motors)
Quick guide
EFF1 Motor for Operating hours exceeding 2,000 hrs per year
EFF2 Motor for Operating hours below 2,000 hrs per year
EFF3 Motors are not recommended to be used.
